PAN纤维水解过程的研究,文献报道有下列几种情况:(1)强酸系统,(2)强碱系统,(3)加压水解,原有这些方法均存在降解难于控制,其产物带强酸或强碱性、或颜色很深,因而限制了它们在织物上的应用。考虑到PAN水解产物具有十分重要的实际应用,如可在油田泥浆处理中用作控失水剂、金属切削中的冷却液、织物整理中浆料、粘合剂和涂料等,同时,对于这类聚合物水解过程中各种条件的影响和机理的研究,均存在进一步探讨之处。基于此,我们采用了路易士酸
PAN fiber hydrolysis process, the literature reported the following situations: (1) strong acid system, (2) strong base system, (3) pressurized hydrolysis, the original existence of these methods are difficult to control the degradation, the product with a strong acid or Strongly alkaline, or deep color, thus limiting their application in the fabric. Taking into account the PAN hydrolyzate has very important practical applications, such as in the field of mud treatment as a fluid loss control agent, metal cutting coolant, fabric finishing in the slurry, adhesives and coatings, etc., while for this The research on the influence and mechanism of various conditions during the hydrolysis of polymer-like polymers are further explored. Based on this, we use Lewis acid
